Last friday I did a cvsup 
src/buildworld/buildkernel/installkernel/installworld/mergemaster on my 
laptop from 6.0-RELEASE to 6.0-STABLE and since the performance of my 
laptop (Dell Precision M70 with a Pentium M 2GHz) is not good. It 
behaves like if the bus was saturated. I noticed that sound skips when I 
play a mp3 with xmms and it also skips when I play dvds (with mplayer, 
ogle or vlc). I have tried to recompile a kernel with apic disabled 
since I had some performance issues with this enabled before 6.0-stable, 
but it didn't fix anything. Does somebody have an idea of what change in 
the FreeBSD sources could be causing this?

Thanks!
